XML文件如下：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<books>
<book name="book1" num="1" > 出版于1991年 </book>
<book name="book2" num="2" > 出版于1992年 </book>
<book name="book3" num="3" > 出版于1993年 </book>
<book name="book4" num="4" > 出版于1994年 </book>
</books>
解析后的结果：
封装model来接收解析后的XML文件数据
JRBook.h文件
#import <Foundation/Foundation.h>
@interface JRBook : NSObject
//书籍名称
@property (nonatomic,copy)NSString * name;
